When using the acpi-cpufreq driver, "/proc/cpuinfo" shows the frequency that is being asked for, not the frequency one actually gets.
One has to use turbostat to know for sure.
For whatever reason, and as mentioned in my previous post, the posted turbostat output is saying that excessive power has caused the slow down. Both the CORE_PERF_LIMIT_REASONS and the IA32_PACKAGE_THERM_STATUS and all of the IA32_THERM_STATUS MSRs are saying this.
